Telephone Ringer
Wed, 4 Apr 2007, 01:09 pmG'day.
There is an old thread about this subject but it wasn't much help to me.
I want a Telephone Ringer to make a real phone ring on the stage in live theatre.
I can't find anything in Australia.
I did find this and it would do the job if I can't find any thing else.
Any body have any other ideas?
Thanks.

It needs more than a battery.
It needs about 50 to 70 volts AC at 25hz.
A local telephone company has donated a power supply out of an old hotel switch board.
It has enough power to ring 50 phones at once.... it is a bit heavy.
PS. We are in a country town, the theatre doesn't have a telephone & mobiles don't work reliably inside the theatre.
